  skos:definition """The Large Angle and Spectrometric COronagraph  (LASCO) instrument is one of 11
instruments included on the joint NASA/ESA  SOHO (Solar and Heliospheric
Observatory) spacecraft. The LASCO instrument is a set of three coronagraphs
that image the solar corona from 1.1 to 32 solar radii. It is convenient to
measure distances in terms of solar radii. One solar radius is about 700,000
km, 420,000 miles or 16 arc minutes. A coronagraph is a telescope that is
designed to block light coming from the solar disk, in order to see the
extremely faint emission from the region around the sun, called the corona.
LASCO was built by an international consortium of four institutions in four
different countries:
- Naval Research Laboratory, Washington, DC
- Max-Planck-Institute for Aeronomy, Lindau, Germany
- Research, University of Birmingham, Birmingham, England
- Laboratoire d'Astronomie Spatiale, Marseille, France

The LASCO electronics box also provides services for an additional experiment
called the Extreme Ultraviolet Imaging Telescope (EIT). Since the two
experiments are closely coupled, status and other general information can be
obtained at this site, but more specific information is available from the EIT
home page (http://umbra.nascom.nasa.gov/eit/).
